Description
WHAT IS IT
A basic step-up (boost) converter module that takes a DC input voltage and boosts it to a higher adjustable DC output voltage. Capable of up to 150W with added heat dissipation, or a solid 100W with natural cooling. Supplied with brass standoffs.
NOT FOR MAINS USE
WHAT IS IT USED FOR
Perfect for running 19V laptops from a 12V battery or vehicle supply . Also useful anywhere you need to step up a battery or DC supply to a higher fixed voltage.
FEATURES
- Adjustable output voltage — set once with the onboard trimmer pot
- Up to 150W output with enhanced cooling, 100W with natural airflow
- Good efficiency — 91% measured at 12V/4.1A in, 18V/2.5A out
- Wide industrial operating temperature range: -40°C to +85°C
- Low no-load current draw: ~19mA typical
- Brass standoffs included for easy mounting and to hold circuit off surface.
- ⚠️ No short circuit protection — fit a fuse on the input
- ⚠️ No reverse polarity protection — series diode recommended on input
HOW DO I SET IT UP?
- Before connecting your load, use a multimeter across the output terminals.
- Power the module from your input supply (10–32V DC).
- Adjust the onboard trimmer pot to set your desired output voltage (12–35V).
- Power off, connect your load, and power back on.
- Check voltage out again with a multimeter.
- If running above 100W, attach a heatsink or add active cooling to the main chip.
